| Abstract | 通过联立求解两中心带输运物质方程和双光束耦合波方程,建立了研究双掺杂LiNbO3:Fe:Mn晶体采用双色光记录光折变体全息的时空特性的动力学模型.数值计算表明,该动态体全息光栅的时空衍射特性与晶体中的折射率光栅相对于干涉场的空间相移有关,该空间相移的取值范围为(-pi,pi),当空间相移的符号发生变化时,双光束之间的能量耦合方向也相应地发生反转.给出了晶体内的等相位线和光强的重新分布. |

| Other Abstract | By jointly solving the two-centre material. equations and the coupled-wave equations,we set up a dynamic model to study the time-space diffraction properties of the photorefractive volume holograms recorded by two colour light in doubly doped LiNbO3: Fe: Mn crystals. Numerical calculations show that, the time-space diffraction properties of the dynamic volume grating are relevant to the relative spatial phase shift between the index grating and the interference field. The spatial phase shift is defined between -pi and pi, the energy transferring direction between the two-coupled beams will be reversed with the reversion of the sign of the spatial phase shift. The winding of equal-phase line and the redistributed intensities of the two-coupled beams inside the crystal are given. |
